Harmony Central: Nine Inch Nails Single Released in GarageBand Format. This is pretty damn cool – if you’ve got Garageband and a bit of bandwidth to spare you can add, remix and just generally mess around with a NIN track. I wonder what sort of license it’s available under – hopefully a Creative Commons one.
Update: Lawrence Lessig has more. Seems it’s not under Creative Commons, which is a shame. Still pretty cool though.
